These cookies are soft, perfectly sweet, and oh so comforting. They are gluten-free, vegan, and simple to make.
Preheat the oven to 350 degrees. Line a baking sheet with a silicone baking mat or parchment paper. Combine flaxseed meal and water in a small bowl. Let sit for 5 minutes to thicken.
In a large bowl, whisk together flax egg, mashed sweet potato, applesauce, maple syrup, and vanilla until smooth. Add flours, baking powder, cinnamon, and salt. Use a wooden spoon or spatula to combine until a soft cookie dough forms.
Use a cookie scoop to portion out dough. Roll into a ball and place on the prepared baking sheet. Bake for 12-13 minutes until light golden brown. Let cool for 8 minutes. Roll cookies in cinnamon sugar mixture (1/4 cup coconut sugar and 1 tbsp cinnamon).
